2 Starting a scan: 1. To perform a scan using Trimble Survey Controller: From the main menu, select Survey and then perform your standard station setup, station setup plus, resection, or refline. 2. From the Survey menu, select Scanning: 3. Define the area for the scan (see next steps for defining polygonal & rectangular areas) use one of the following methods, and see below for preset buttons that you can use: Polygon framing: 1. If is displayed, tap to set the Polygon framing mode. 2. Tap on the video screen to define the first corner of the polygon. Tip: We ve found that it s faster & easier to sight the vertexes/points along the polygonal frame area from the instrument, then tap the center of the screen to create a new vertex (polygonal frame point). 3. Tap again on the video screen to define the second vertex. You must enter at least three vertices to define a polygon scan frame. 4. If required, drag-and-drop the last vertex to move it, or select the vertex and then tap undo ( ) to remove it. You can do this only with the last vertex.

3 Rectangular framing: 1. If is displayed, tap to set the Rectangular framing mode. 2. Tap on the video screen to define the first corner of the scan rectangle. 3. Tap again on the video screen to define the opposite corner of the scan area. 4. If required, drag-and-drop the vertices, or click and drag the sides of the scan frame to resize the scan rectangle. Define the point density for the scan area: 1. Tap scan properties ( ). 2. Define the scan properties. You can select one of the following methods: - Horizontal and vertical distance interval at a given distance (to define a maximum density at the furthest scan distance: Click the Menu Arrow next to the At Distance value, aim at the furthest surface/object that you would like scanned at the defined HD & VD interval and tap Measure this will take a DR/Reflectorless measurement any objects closer to the VX will be scanned more densely, up to.033 US Survey Feet/1cm): - Horizontal and vertical angle interval - Total number of points in the scan - Time to complete 3. Enter the parameters to define the scan density. 4. Tap Start. Copyright California Surveying & Drafting Supply. Not to be copied or distributed without permission. 3

4 Important Notes: The camera is not coaxial with the telescope. For accurate framing at close range, define the At distance setting, which helps to draw the scanning frame in the correct position. The time to complete a scan is an estimate only. Actual scan times will vary depending on the surface or object being scanned. Scan time is increased if there are areas within the scan that will not return an EDM signal. Where possible, try to minimize blank space in the scan area. Defining the scanning grid through distance intervals assumes that the scanning object is a constant distance from the instrument. In other cases, the scan points will not constitute an even grid. When you perform a scan with the Trimble VX through a robotic connection, Trimble recommends that you stay within the range of the radio link to ensure that all necessary data is collected successfully. If you lose the radio link, the remainder of the current scan line will be skipped. You can scan a full 360 horizontally. The vertical range is approximately between 3 36' (4 gon) and 150 (166 gon). You can use the preset buttons to help you define the scan area. These preset buttons are available for Polygonal framing: Toggles between rectangular and polygon framing mode. When selected, the polygon framed area is shaded red. Deletes the scan frame from the screen. When the 'cross' is grey, the delete function is not available. Undoes the previous vertex. When the 'arrow' is grey, the undo function is not available. Copyright California Surveying & Drafting Supply. Not to be copied or distributed without permission. 4

5 These preset buttons available for Rectangular framing: Toggles between rectangular and polygon framing mode. Toggles between the current frame and the complement of the current frame. Tap this button to change the horizontal extents of the scan so that the horizontal scan area is the opposite of the original frame; it is the larger part of the horizontal circle. The vertical extents of the scan area do not change (Tap this button again to change the horizontal extents of the scan so that the horizontal scan area is the original frame; it is the smaller part of the horizontal circle. The vertical extents of the scan area do not change). Automatically defines a rectangle from the highest to lowest vertical angles in the current horizontal position. To resize the scan frame, drag one of its sides or vertices. This is useful for quick-framing an object (for example, a facade), in front of the instrument. Automatically defines a large horizontal rectangle through the majority of the horizontal circle. To resize the scan frame, drag one of its sides or vertices. This is useful for quick-framing an object that surrounds the instrument. Deletes the scan frame from the screen. When the 'cross' is grey, the delete function is not available. Undoes the previous vertex. When the 'arrow' is grey, the undo function is not available. Copyright California Surveying & Drafting Supply. Not to be copied or distributed without permission. 5

6 Capturing the image(s) displayed in the video frame of the scanning window: Links to the Scan Properties form where you can define the parameters of the scan. You can define the density of scan points within the frame area by distance intervals, angle intervals, the total number of points, or the scan time. Controls the brightness of the video image on the controller screen and consequent captured images. Controls the contrast of the video image on the controller screen and consequent captured images. Controls the level of white balance in the video image on the controller screen and consequent captured images. Set the file name. File names are automatically incremented from the start file name. Set the image size. The image captured is always the same as the video display on screen. Not all image sizes are available at all zoom levels. Set the compression of the image. The higher the quality of the image, the larger the file size of the captured image. (XL) Captures an extra large image (2048x1536). XL is available only when zoomed to extents 1:1. (L) Captures a large image (1024x768). L is available only when zoomed out to extents 1:1 and 2:1. (M) Captures a medium image (512x384). M is available only when zoomed in to 1:1, 2:1, and 4:1. (S) Captures a small image (256x192). S is available regardless of the zoom level. Launches the Panorama function where you can automatically capture multiple images for a defined scan frame. Define the Image size and Compression, enable Fixed exposure to fix the exposure to the settings at the time you tap Start, define the Image overlap and then tap Start to begin taking the images. Tip - The exposure is fixed when you select Start. When using the Panorama function with Fixed exposure enabled, point the Trimble VX to the location that defines the camera exposure that you want used for all panoramic images and then tap Start.

7 Point cloud color: Color Cloud color Station color Scan color Grey scale intensity Color coded intensity Show points... with the color of the clouds they belong to with the color of the stations they belong to with the color of the scans they belong to using the gray scale defined by their intensity using the color encoded intensity You can navigate/zoom around the video frame in the scanning window. The navigation controls are as follows: + - Pan Options Zoom in. There are four levels of zoom available in the video window. Zoom out. There are four levels of zoom available in the video window. Activate tap-and-move functionality in the video window. Zoom out to the full extents. Display point clouds controls the option to display the point cloud over the scan. Color controls the color of the point cloud. Point size controls the width of the pixel displayed in the point cloud.
